Fibre cement profiled sheeting from Marley Eternit has brought a sympathetic treatment to the roof of a former storage barn that has been transformed into luxury holiday homes.

Fibre cement profiled sheeting from Marley Eternit has brought a sympathetic treatment to the roof of a former storage barn that has been transformed into luxury holiday homes Bath-based architect Ian Bower RIBA specified Marley Eternit's Profile 3 roofing in Thrutone Blue not just because it was in keeping with the surrounding buildings and rural location in deepest Wiltshire but because it was visually softer than the rusting galvanised steel it was replacing

Ian had seen a sample and case study of Marley Eternit's profiled sheeting, as used to roof and clad another architect's home/office, in the architecture gallery at the Victoria and Albert Museum in London.

"I looked at a bituminous-based corrugated roofing sheet at first but I didn't like the look".

"It was too hard and not so robust or perhaps as long lasting and the colours not subtle".

"I wanted something with a visual softness," he said.

"The fibre cement was pricier but lower maintenance and thermally and acoustically efficient so I persuaded my client that she needed to use this material." His client was Stephanie Szakalo, owner of The Stone Barn in Norbin, Wiltshire, 10 miles from Bath, who wanted a new lease of life for a 100-year-old derelict stone-built storage barn in her garden adjacent to a working beef farm".

"We managed to find a design to work not only in satisfying the rigorous requirements of the local planning office, made more so because of our location in a Green belt area, but more importantly as two stylish and unique houses for holidays," she said.

Roofing contractor Andy Green of Industrial Building Solutions brought the same attention to detail to the installation of the Marley Eternit sheeting as Stephanie brought to the internal specification.

Indeed, he was so pleased with the result he has entered the project in the National Home Improvement Council's 2006 award scheme, in the Roofing Excellence category that looks for the best example of upgraded roofing stock that shows compatibility with the environment plus high quality workmanship.

Marley Eternit's profiled sheeting on The Storage Barn meets both criteria in spades.

Inspection by the architect and structural engineer had concluded that the timber framework and most of the close boarding of the original barn could be retained to allow the finished building to maintain its former character.

However, the roof presented two areas of concern - it had to be insulated to a minimum "U" value of 0.20 and be in keeping with the surrounding buildings and rural location.

Several options were reviewed before all concerned agreed on Marley Eternit's Profile 3.

Additional timbers had to be installed to close the gaps between supports and as the close boarding was being retained, a 1,000-gauge vapour control layer was laid from ridge to eaves.

To form the insulated cavity, a spacer bar system and 10.5kg non-hygroscopic glasswool insulation quilt was used.

Fitting of the Marley Eternit sheets was the next stage and as the sheets could not be mitred in position because of the 30 degree pitch, each was temporarily positioned, marked and then removed to the scaffold platform for mitring before being re-positioned around five roof lights.

The roof sheet crowns were pre-drilled with an oversized hole to allow for thermal movement prior to attaching the sheets using a self-drilling fastener to the spacer bar.

For aesthetic purposes, all the fastener heads and washer faces were powder coated in black to match the washers.

At the ridge, a two-piece, close-fitting Marley Eternit ridge was selected in the Thrutone Blue colour, complete with finials to each gable end.

At the eaves, the Marley Alutec cast aluminium gutter was selected and polyester powder coated to give the look of a traditional cast iron product.

Marley's cast aluminium rainwater pipes were similarly deployed, fixed back to the vertical treated close boarding above the gully points".

"This was an incredibly rewarding project to work on and we are delighted with the results," said Andy. Request a free brochure from Marley Eternit ...
